While psychologist was teaching stress management to the class. He raised a glass of water. Seeing this everyone expected that he is going to ask, "Half empty hal full..!!" But instead he asked, "How heavy is this glass of water?"Many called out the answer that it ranged from 8 oz. To 20 oz. Now psychologist replied"This absolute weight of glass doesn't matter. what matter is how long I hold it.if I hold it for a minute it's not going to be problem. if I have to hold it for an hour then I will feel ache in my arm. if I hold it for a day, my arm will feel numb and paralyzed. in all the cases the weight of glass doesn't change, but longer I hold heavier it becomes."He continued.. "Similar are stress and worries.if you think about them for a while, nothing happens. if you think about them a bit longer, they hurt. and if you think about them all day long, you feel like paralyzed or incapable of doing anything." 
It's important to let go off your stresses. Don't carry your burdens and stress into evening and then night.
